MICRCodeDetectionCommand Class

Summary

Automatically detects a Magnetic Ink Character Recognition (MICR) zone in a document image.

Syntax
C#
VB
Objective-C
C++
Java
public class MICRCodeDetectionCommand : RasterCommand 
Public Class MICRCodeDetectionCommand  
   Inherits RasterCommand 
@interface LTMICRCodeDetectionCommand : LTRasterCommand 
public class MICRCodeDetectionCommand extends RasterCommand 
public ref class MICRCodeDetectionCommand : public RasterCommand   

Remarks
  • This command searches inside a given LeadRect zone (set using the SearchingZone property) and detects a MICR code.
  • Get the detected zone by calling the MICRZone property.
